LAMP-SHADE CONSTRUCTION.

- Application filed September 5, 1922. Serial No. 586,111;

To all whom it may concern:

Be it knownthat I, SERAPHINE F. BAU- WENS, a citizen of the UnitedStates, .resid-.

The object of the invention is to facilitate the ready securement of thesilk or other decorative cover material on the supporting framethisparticularly where sharp inward turns or drops are provided in the frameto produce what is known as the multiple deck efiect in the finishedshade, when the cover material is, in fact, one continuous piece,instead of being in separate pieces as in real multlple deck designs.

The invention consists in means for attaining the foregoing and other obects; which can be easily and cheaply made; which is very satisfactoryin use and is not readily liable to get out of order More particularly,the invention consists in many features and details of constructionwhich, will be hereafter more fully set forth in the specification andclaims. I i u Referring to the drawings in which like numerals designatethe same part throughout the several views:

Figure 1 is a side elevation of a fancy shade constructed in accordancewith this invention 1 in its preferred form.

Figure 2 is a plan view of the shade of- Figure 1. o

Figure 3 is a central sectional detail view on the line 38 of Figure 4,showing from the interior the construction of the device.

Figure 4 is a plan view of the frame on which the shade of Figure 2 isconstructed.

Figure 5 is a sectional'detail View on the line 55 of Figure 4.

Figure 6 is a fragmentary detail view of the stretchable part of theseparable cover material securing ring.

The invention is applicable toany shade or cover of the mushroom orumbrella type in which the exterior cover material 10 of the finishedshade rests upon and is supported by a frame having radially disposedribs 12 connected at their centers by a small the ring 24, on the ribs12 ring 14 adapted to it over a lamp or lamp chimney, as the case maybe, and connected at their outer endsby another ring 16, defining theoutside limits of 1 the finished shade.

'In the .particular case illustrated in the.

drawings, the ribs 12 of the frame are, intermediate between the rings14 and 16, sharply, inwardly and downwardly reversely curved at thepoints 18, all lying in the arc of and upwardly formed curves 20 and 22which, when the silk or other cover material 10 is stretched tightly inplace, produces what is known asthe double deck effect, viz: on lookingat the outside of the shade, the .observerfgains the impression that thesilk 10, covering the curved portions 20, extends through an annularopening on the line of curved points 18 into the interior of the shade,and that the portion of silk covering the curves 22 ends at opening ator adjacent to the circle of points a circle concentric with the center.of the shade so as to leave the outwardly a supposedv 18, which allowsthe lower portion of cover material, heretofore. referred to, 20 to passunder into the shade. The problem solved by this invention isto sofasten the silk or other cover material 10 of the shade at or adjacentto the circle of points 18 that although only one continuous piece ofcover material is used over the shade, this multiple. deckefi'ect,described and shown, is produced. The problem is solved by placing onthe outside of the frame heretofore described, and underneath the cover10 an'annular material support, rigidly attached to the rib members 12,the samein the case here illustrated-taking the form of a continuousannular, ring 2 1 soldered, brazed or otherwise permanently secured inplace as shown and providing in connection therewith an externalstretchable ring 26 adapted to be snapped over the cover material 10below the annular material support, in the particular case hereillustrated to engage it on its side farthest from the center of theshade, with the result that the spring tension of this ring 26, providedin the particular case here illustrated by a retractal spring 28interposed in its length, securely locks the cover material 10 over andbelow the sta tionary ring 24. The result of this construction by whichthe cover material passes in an S over the rings is that even though theI upon the height tension on the various parts be suflicient to pull thecover material 10 down into depressions 10 and 10 between the ribs 12,as clearly shown in Figure 5, the entire cover member 10 presents asmoothly stretched efiect and gives the desired multiple deckconstruction appearance.

In the drawings, the shade is shown with only two decks, one above, theother below ring 26; but, obviously, the number of decks may bemultiplied indefinitely depending and size of the shade.

In actual practice, the structure is very advantageous in that if covermaterial 10 becomes soiled, the operator can easily remove the ring 26and, after removing the sewing or other conventional cover fastening(not entering into this invention), attaching the cover to the rings 14cand 16, remove the cover for cleaning or replacement at will.

The drawings show the'ring 14 supported on spokes 3O radiating from acentral block 32, the same being a conventional shade centerconstruction not entering into this invention.-

The use of the word ring in the specification and claims is not intendedto limit in place permanently sewed to the top and bottom such part to atruecircle.

An additional advantage of the ring construction is-that after the covermaterial has been placed over the ribs and the rings are but before thematerial has been of the frame, the operator can pull the material alongthe ribs of the frame, the material 'in this operation sliding throughbe- V tween the rings without its being necessary to remove the springring or rings. In this operation, the coupling 28 permits the ring 26 tostretch enough for this purpose without its being necessary to removethe entire ring.

1. A lamp shade comprising, a cover, an

inwardly stepped wire frame having a support band at the bottom of eachstep, and

an attachable member drawing said cover over said support band into thebottom of said steps.

' 2. In a lamp shade of the umbrella type, a wire frame having radialribs each having intermediate its length an inwardly bent reverse curve,a cover comprising a continuous body of material stretched over saidribs and into said reverse curves, and means extending around the frameover the ribs, said means securing the cover material to said ribs at.said reverse curves.

3. In a lamp shade of the umbrella type, a wire frame having radial ribseach having intermediate its length an inwardly bent reverse curve, acover comprising a continuous body of material stretched over said ribsand into said reverse curves, and a removable ring securing the covermaterial to said ribs at said reverse curves. o I

4. In a lamp shade, an inwardly stepped wire frame, a cover stretchedover said frame and attached thereto at the top and bottom, and meansdrawing said material into the steps of the frame, said means'comprisinga wire loop and a resilient member fastened to and encompassing saidloop for the purpose of urging said ends together.

5. A lamp shade of the umbrella type comprising, a wire frame havingradial ribs,

each rib made intermediate its length in-' a wire frame including radialribs inwardly reversely curved intermediate their length, vand a loopfor securing the cover to the ribs at the bottom of said curves, acoil-spring fastenedto and encompassing the opposed ends of said loop,whereby the loop is capa-* ble of being slipped over the outward curvesof the ribs and is drawn by said spring into the bottom of said reversecurves.
